[Boost-users] Question about boost.json and unescaped control characters

Hi there, Is it possible to "make" the boost.json parser allow unescaped control characters in JSON string values? It seems to me that `allow_invalid_utf8` and `allow_invalid_utf16` parse_options doesn't help with this. I also looked at the source code of `parse_string` function and it seems to me that even if I provide a handler with `on_string` member function the parser will still throw an error because of the unescaped control characters before calling `on_string`. Maybe my only option is to escape such control characters before giving the JSON data to the boost json parser? Thanks, Pavel.
